In ΔTUV, the measure of ∠V=90°, the measure of ∠U=70°, and UV = 9.6 feet. Find the length of TU to the nearest tenth of a foot.

Nutka1998 [239]

28.1 feet

explaination

\cos U = \frac{\text{adjacent}}{\text{hypotenuse}}=\frac{9.6}{x}

cosU=

hypotenuse

adjacent

=

x

9.6

\cos 70=\frac{9.6}{x}

cos70=

x

9.6

x\cos 70=9.6

xcos70=9.6

Cross multiply.

\frac{x\cos 70}{\cos 70}=\frac{9.6}{\cos 70}

cos70

xcos70

=

cos70

9.6

Divide each side by cos 70.

x=\frac{9.6}{\cos 70}=28.0685\approx 28.1\text{ feet}

x=

cos70

9.6

=28.0685≈28.1 feet

Type into calculator and roundto the nearest tenth of a foot.

Write a quadratic equation in standard form with the given roots

stich3 [128]

${x}^{2} - \frac{15x}{2} + \frac{7}{2}$

Step-by-step explanation:

So we go backwards, since we have x= 1/2 , 7

$(x - \frac{1}{2} )(x - 7)$

Now we have to foil to get the quadratic

${x}^{2} - 7x - \frac{1}{2} x + \frac{7}{2}$

We must simplify the terms

${x}^{2} - \frac{14x}{2} - \frac{x}{2} + \frac{7}{2}$

Our final result comes out to be

${x}^{2} - \frac{15x}{2} + \frac{7}{2}$
